Good work. Thanks for sharing. The included capacitive phase conversion is a refreshing approach.

Cheers and KneeDeep

Fausto,

Power wise, you are showing less than 40 mW out and 6W in for one set of generator coils, which is less than 5% of the input power consumption! Multiplied by 7 for a full set of generator coils, this would give 280mW / 0.28W. I would not expect your input ammeter to deflect noticeably with lamp load or short circuit for one or two coil sets, as the supply is being very lightly loaded. Try adding the remaining coils and repeat the same test. The load will still only be consuming very low power but you may detect a deflection to the RHS on the meter as more coil sets are added. Its important to think in terms of input and output power / energy consumption, not just amp draw.

You are right it is very low power but its a principle issue for now to give some clues towards tuning the rig.  Forget the i/p power for now its really not important. That can be dealt with later. eg collect the driver coils BEMF and send that off to the dump cap might find an extra watts or two.

For now take  the drive up to 1500 rpm then retune the generator coil its still not tuned correctly more "sniffing" the power.  When its correctly matched the volts will be a LOT higher out to a dump cap and the waveforms very symmetrical.
